FUNCTIONAL DEVICE OPERATION
OPERATING MODES
The power up sequence is shown in Table 27. VCOREDIG, VSRTC, and VCORE are brought up in the pre-sequencer startup.
Once VCOREDIG is activated (i.e., at the first-time power application), it will be continuously powered as long as a valid coin cell
is present.

Notes
37.
The switchers SWx are activated in PWM pulse skipping mode, but allowed when enabled by the startup sequencer.
38.
USB supply VUSB, is only enabled if 5.0 V is present on UVBUS.
39.
The following supplies are not included in the matrix since they are not intended for activation by the startup sequencer: VCAM, VGEN1,
VGEN3, VVIDEO, and VAUDIO
40.
SWBST = 5.0 V powers up and does VUSB regardless of 5.0 V present on UVBUS. By default VUSB will be supplied by SWBST.
